INKINGY DEVICE.

SPECIFICATION forming part of Letters Patent No. 449,110, dated March31, 1891. Application filed November 9, 1889i Serial l lo. 329,721. (Nomodel.)

To all whom it may concern:

Be it known that I, MATTHEW J. DOLPHIN,

of Brooklyn, in the county of Kings and State of New York, have inventednew and useful Improvements in Inking Devices, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description. I My invention relates to an improved inker, andhas for its object the production of a simple and effective device whichrapidly, continuously, and evenly feeds ink to the'marker of amarking-machine; and to this end it consists, essentially, in a suitableink reservoir or holder,a feeding-surface connected to said reservoir orholder, a regulator for governing the flow of the ink from the holder orreservoir, an inking-roller, and an intermediate roller for feeding theink .from the feedingsurface of the inking reservoir or holder to saidinking-roller.

It also consists in auxiliary spreading-rollers for aiding the evendistribution of the ink upon the inking-roller; and it furthermoreconsists in the detail, construction, and arrangement of the parts, allas hereinafter more particularly described, and pointed out in theclaims.

In specifying this invention reference is had to the accompanyingdrawings, forming a part of this specification, in which like lettersindicate corresponding parts in all the views.

Figure 1 is a top plan view of my improved inker. Fig. 2 is an elevationof the parts as illustrated in Fig. 1. Fig. 3 is a horizontal sectionalview taken on line as as, Fig. 2, particularl y illustrating therelative arran gem ent of the rollers of my improved inker. Fig. 4 is asectional view taken on line y y, Fig. 3. Fig. 5 is an elevation of thedetached inkfeeding regulator. Fig. 6 is a top plan view of theregulator illustrated in Fig. 5. Fig. 7 is an inverted plan view of thefilling-piece or cover of the ink-containing reservoir. Figs. 8 and 9are respectively top and inverted plan views of the detached extremityof a support for my inker, illustrating particularly the fine adjustingdevice therefor. Fig. 10 is an elevation of an evening-roller foreffecting the even distribution of the ink, and Fig. 11 is a detailelevation illustrating an additional evening-roller.

The table or other support A for the inking device may consist of thesupporting-table for a marking-machine of the usualor any specialconstruction. Mounted upon this table is the bracket B, which preferablycarries the several parts of my inventionnamely, the feeding orink-containing roller 0, the inking or spreading roller G, theintermediary roller F, and the eveners H and J.

Supported in suitable proximity to my inker is the marker a, which maybe of any suitable form, size, or construction, but is here illustratedas the one described and claimed in the patent of August Bertram, No.408,401, issued August 6, 1889. This marking-roller is mounted upon theshaft a, and consists of the continuously-revolving portion or drum aand the printing portion or marker a normally at rest until a clutch ais operated by the advancing letter to connect said marker to drum a Themarker then makes a com plete revolution, whereupon the clutchdisengages the same from the drum, and the rotation of the marker ceasesuntil the clutch is again operated by another letter.

The ink-containing roller 0 is of substantially the same construction asthat illustrated and described in my pending application, Serial No.823,946, filed September 14:, 1889, and possesses the additionalfeatures of advantage-namely, that the same may be readily removed fromthe remaining portion of the inker without stopping the operation of themarking-machine or soiling the hands of the operator, and that the feedof the ink is more readily and positively controlled. This roller 0, asbest illustrated in Fig. 4, is mounted on a bracket 0, hinged at c tothe bracket B, and is provided with an ink-containing reservoir orreceptacle, which preferably consists of a cavity or recess 0', formedwithin said roller by constructing the same of tubular shape. Passingfrom the interior to the outside of said roller 0 are a suitable numberof openings or passages 0 through which the ink is fed to an outsidefeeding-surface C The preferable manner of rendering this roller 0readily removable from the remaining portion of the inker consists inrotating the same frictionally and mounting it upon a spindle C formedor provided on the bracket B.

This spindle is engaged bya socket 0 formed in an upwardly-extending hub0 rigidly secured to the base C of the inking-roller. As will bepresently described, the ink is fed to the cavity G and the flow thereofis governed by a regulatorD of suitable form and construction. Thepreferable form of regulator consists of a sleeve provided with openings(Z, registering with the openings 0 of the roller (I. As bestillustrated, these openings are formed at one side thereof with thegrooves (1 leading therefrom.

hen the sleeve D is inserted to its normal position within the roller(J, no flow of theink is allowed, since these parts are so formed thatthe openings 0 and (l are out of alignment with each other. However, byturning the sleeve D within the roller 0, as will be presently setforth, the grooves 61', and finally the openings (Z, maybe registeredwith the openings 0' These grooves are a feature of great advantage,since when in operation the ink-containing roller is revolved withconsiderable rapidity, and the centrifugal force generated causes theink to flow with a greater force than desired when the openings 0 and (Zare registered with each other, even though, as illustrated, theseopenings are few in numher and of comparatively small size. However, byadjusting or partially rotating the sleeve D the flow may be regulatedto a nicety, as desired, since as the sleeve is adjusted the grooves dare registered with the openings 0 and as these grooves grow graduallylarger in area a consequent increasing llow of the ink is produced untilthe desired feed is produced. This feature is of particular advantage,since it enables my inker to be used with dilferent kinds of ink, asmust necessarily be the case when the same is desired for use upondifferent printing or markin g machines.

Provided at the upper part of the sleeve D is the disk or plate D,preferably formed integral therewith and provided with the openin g Dinto which the ink is readily inserted without withdrawing said sleevefrom the roller G. Above said disk is the filling-piece or cover E,which is secured to said disk by means of suitable lugs or pins e,secured to said disk and engaging openings 6' in the cover E. As bestseen in Fig. 2, the said filling-piece is provided with theoutwardly-projecting pin 0 which engages a right-angular slot or cut-outc in the said roller C, securely retaining the parts together andallowing the adjusting movement of the sleeve D within the roller 0 tobe readily determined by the position of said pin within the slot. Itwill be noted that one extremity of the slot or guide 0 extendshorizontally and the other extremity extends vertically to the edge ofthe sleeve G to admit the entrance of the pin e Rig-idly secured to thedisk D is a projecting pin 1), passing through an opening in thefilling-piece E, and provided at the top with a nut D screwing thereuponand firmly securing said filling-piece in its desired position upon thepin e.

In order to best cover the opening D I provide on the under side of thefilling-piece E the rubber packing D which tits over the opening DDiametrically opposite to said piece D is a like piece D, which bringsabout the even bearing of the filling-piece E d prevents cramping of theparts.

Contacting with the feeding-surface of the roller C is the intermediaryroller F, which is preferably provided with a face of gelatine or othersuitable yielding substance, and is revolved continuously by means ofsuitable gearing or otherpower-transmitting m echanism F, connecting theshaft of said roller to the shaft a of the marking-roller a.

The ink-containing roller 0 is preferably revolved by friction with theroller F, and this can be increased at will by loosening the screw a,forcing together said rollers, and then tightening the screw. Contactingwith the roller F, and also with the marker at at each revolutionthereof, is the ink-distributing roller G, which thus feeds the ink tothe marker. This roller is provided with a face of. felt or othersuitable yielding material, and is movable toward the auxiliary roller Fin order to increase the friction between said rollers and renderpositive thedriving of the roller G by the roller F.

As best seen in Fig. 4, the pivotal pin G of the roller G is providedwith its lower extremity screw-threaded and engaging a sliding piece g,working in a slot b in the under side of the bracket B. This block g isprovided with the upwardly-extending portion 9, of less width than thebase of the sliding piece g, and guided in the slot Z). \Vhen thepivotal pin G is screwed clown- Ward, the face f, formed upon saidblock, is drawn against the face I) of the bracket B, and the frictionof the parts holds said block and pin in their adjusted position. Inorder to facilitate the revolution of the roller G, it is advisable tointerpose a washer between the same and the bracket B, as, while it isnecessary that the said roller should be held in its adjusted position,it is also necessary that it should revolve with great case, so that butlittle wear will be occasioned. This arrangement of the i nk-con tainingroller, inking or distributing roller, and auxiliary roller brings abouta very even distribution of the ink, which is an essential point, andhas heretofore been but imperfectly produced. This even distribution isfurther aided by an evener H, which preferably consists of a rollerjournaled in a bracked II, mounted upon the spring I, which is securedto a post 1, provided upon the bracket B. The evening-roller H thusbears against the distributingsurface of the ink-containing roller witha constant pressure and evenly spreads the ink thereupon before it istaken or wiped oif by the roller F.

IIO

In some cases it frequently becomes advisable to use an additionalevening-roller, and

' this I prefer to mount so as to operate upon the intermediary rollerF. This second evening-roller J is preferably movable up and down theperiphery of the roller F, and this desirable result I obtain by looselymounting the said roller upon its pivotal pinj, forming a cam-face Jupon the lower extremity thereof, and engaging the same with a pin orlug j, provided upon its supporting-post.

The ink-distributing roller is preferably revolved by friction, and itwill be seen that upon its operation the said evening-roller J is movedup and down, according to the engagement of the elevation or depressionof its uneven surface with the pin 3'.

In order to render my inker effective, it is necessary that the same beadjustable toward and away from the marker D, and this is preferablyproduced by pivoting said bracket by a pin B, which engages a slot 15 inthe bracket. In order to produce the best results, itis necessary,however, to effect a fine adjustment of the bracket, and accordingly, asi n myprevious application, I provide therein a slot B which engages apin B", projecting from the frame A. Guided in the bracket B andentering the slot B is a screw E the extremity of which bears againstthe npwardly-projectinglug or pin B. When desired to adjust the bracketB upon the table A, the screwor bolt B is loosened and the screw B isthen operated to adjust the same to the desired position, whereupon thebolt B is screwed downward, retaining the bracket in its desiredadjusted position.

The operation of myinventionwillbe readily perceived from the foregoing.and it will be readily understood that the feeding of the ink ispositive, and that the same is distributed very evenly upon the die ormarker D, thus rendering the impression of stamp thereof clear andeffective. It will, however, be understood that considerable change maybe made in the relative construction and arrangement of the parts of myinvention without departing from the spirit thereof. Hence I do notlimit myself to its precise described form and construction.
